T0 all whom it may concern:

Be it known that we, SILAs E. BAILoR and FRED M. AsHE, citizens of theUnited States, residing at Tarkio, in the county of Atchison and Stateof Missouri, have invented new and useful Improvements in Cultivators,of which the following is a specification.

Our invention relates to two-row shovelcultivators; and .our inventionconsists in,first, providing four gangs connected together in two pairs,said pairs being movable-laterally and independently of each other andeach gang being vertically movable independently of the other gangs;second, novel means for moving the pairs of gangs laterally, eithertogether in the same direction or separately and independently; third,means for causing the beams to always remain perpendicular to the axleregardless of their positions, whereby the shovels will always act uponthe soil at the proper angle; fourth, novel means for lpreventing themiddle shovels from clogging up with trash in the first plowing. Saidmeans consists in extending one of the middle shovelbeams rearwardly, sothat the shovel carried thereby is behind the other middle shovel;fifth, novel means for changing the angles of the pivot-axle-carryingwheels either simultaneously with side movement of the gangs orindependently thereof; sixth, in a threehorse cultivator novel devicesfor attaching draft-eveners to the tongues.

Referring now to the accompanying drawings, Figure 1 is a plan View of acultivator embodying our invention, the draft-eveners being indicated bydotted lines and the swingletrees omitted. Fig. 2 is a rear elevation ofthe cultivator, the seat being omitted and the seat-bars in section.Fig. 3 is a side elevation of the cultivator, the right-hand wheel beingomitted and the spokes of the left-hand wheel omitted. Fig. 4 is anenlarged detail showing one of the gang-sleeves in section and the tworods supported thereby, one of the latter being broken away. Fig. 5 isan enlarged detail view of our preferred adjusting device for changingthe angles of the shovel-Shanks to their beams. Fig. 5*L shows the endof the beam, the casting 39 being removed. Fig. 6 represents a modifieddevice for the same purpose. Fig. 7 is an enlarged detail plan of thetop sector and the lever acy tuated thereby. Fig. 8 is an enlargeddetail side elevation of the sectors, the lever actuated thereby, itsfulcrum, and its connection to the sway-bar. Fig. 9 is an enlargeddetail rear elevation of bracket 81, hanger 89, and the upper ends ofthe foot-levers, the seat-bars being sectioned. Fig. 10 is an enlargedside elevation of the left-hand footlever, its rock-shaft, and theconnections of the latter to the sway-bar, the sway-bar and the bearingsof said shaft being in section.

The frame of the cultivator consists of' a double-strength axle-bar1,connected together at their ends; two tongues 3, secured to saidaxle-bars by bolts 1; two braces 5, connecting the front axle-bar to thetongues 3, respectively; a transverse cross-bar 6, connecting thetongues, and two longitudinal central bars 7, the front ends of whichare secured to the cross-bar 6 and also to the axle-bars by means of aninverted-U-shaped connection 8, the rear ends of said bars forming asupport for the seat 9.

rIhe details of the frame construction are as follows: Cast integralwith blocks 2, respectively, are vertical sleeves 10, through which passthe upturned ends of the pivot-axles 11. Secured by U-bolts 12 to theaxles 11, inside of the wheels 13, are castings 14:, to which aresecured two forwardly-extending' arms 15, termed hereinafter thewheel-arms. These arms are connected together pivotally by a transversebar 16, termed hereinafter the sway-bar. The sway -bar when movedlongitudinally by means described hereinafter changes the angles of thecarrying-wheels 13 by acting upon the wheel-arms 15.

The inverted-U-shaped coupling 8 has its ends bolted betweenthe'axle-bars 1, and secured to the top of said coupling' is a smallU-shaped connection 17, which is riveted to the respective seat-bars 7.The bolts 18, which pass through the ends of coupling 8, are utilizedfor securing the inner ends of braces 5 to the front cross-bar. Saidbraces 5 pass obliquely beneath the tongues 3, to which they are securedby bolts 19. The forward ends of said braces are bent inwardly, as shownat IOO l 20, and are again secured to the tongue by bolts 21. In thebent portions 2O are boltholes 22, which receive pivot-bolts 23, Fig. 3,for supporting the evcners 24. (Shown in dotted lines.) The object inpivoting' the eveners outsile of the tongues instead of directly to thetongues is to permit the inner arms of the eveners to be fully twice aslong as their outer arms, so that the draft upon each of thev threehorses will be equal. rl`he three swingletrees are not shown. The lowerends of the pivot-bolts of the eveners 24 are held by the front ends 25of braces 25, which extend back under the tongues, and their rear endsare secured to the axle-bars l by bolts 4. Secured by these bolts 4 tothe rear ends of the tongues, respectively, are two V-shaped braces 26,the ends of which are bent laterally and horizontally to providebearings for four vertical rock-shafts 27, the lower ends of which arebent and extend forwardly and are connected to the gangs in the mannerhereinafter described. Secured to braces 26, near the ends thereof, aretwo pairs of downwardly and forwardly extending braces 28, the forwardends of which are secured to the transverse anglebar 6 by bolts 21.rIhese braces 28 may be integrally connected at their front ends, asshown. Directly behind said rock-shafts 27 are four standards 29, thelower ends of which are bolted tothe front axle-bar. The upper and lowerends of said standards 29 are bent forwardly to forni bearings 30 and 31for said rock-shafts 27. The upper ends of said rockshafts are connectedby downwardly and forwardly extending cranes 32 to the forward ends ofthe forwardly-extending portions 27 of said rock-shafts. rlhecombination of each crane 32, rock-shaft 27, and the forward extension27 of the latter is termed hereinafter a front crane. The four frontcranes support the forward ends of the four gangs, as presentlydescribed. Mounted on the forward upturned end of eachfront forwardextension 27 is a clip 33. The right-hand pair of front cranes 32support, by means of two clips 33,

an arch-rod 34, by means of which the front' ends of the right-handfront cranes are con- 5 nected.

Mounted on the respective ends of cach archrod 34 are two gang-couplings35. Each of said couplings is right angular in form, having a horizontalportion and a depending portion, the horizontal portion havingrearwardly-projecting' eyes 35', through which arch-rod 34 passes. Thedepending' portion of each coupling has two forwardly-projecting eyes35". Through each pair of coupling-eyes 35 passes the upper end of ashovelbeam 36, it being understood that there are four gangs of shovels,and accordingly four beams. Bolted to the rear end of each beam 36 aretwo beams 37, and the shovel-Shanks 38 are adjustably connected theretoby devices shown in detail in Fig. 5 or Fig. 6. Fig.

5 illustrates the preferred form. In this form the shank 38 instead ofbeing secured directly to the beam 37 hasa casting 39 interposed betweenitself and the beam, and all three of said parts are secured together bya pivotbolt 40. The upper end ofA the shank is engaged by lugs 39 and arib 39 of casting 39. so that said casting is operatively a part of theshank. Between two ribs 39' on said casting is a movable iron block 41,in which .is a diagonal slot 42, through which projects a stud-bolt 43,secured to the beam 37. On bolt 43 is a nut 44. Vhen this nut isloosened, the shank 38 may be turned at different angles to the beam37by sliding the block 41 to the right or left, the former movement tomove the shovel forward, the latter movement to move it back. When nut44 is tightened, the shank is held rigidly in the usual manner. In themodified device shown in Fig. 6 for the same purpose the upper portionof the shank is made in two pieces 45 and 46. The upper piece 45 isrigidly secured to the beam 47 by a bolt 48. The upper end of the shankproper, 46, is provided with ribs 49, between which is a slotted block50, through which projects a stud-bolt 51, secured to the piece 45. Theadjustments are effected by loosening the nut 52 and turning the shank46 about its pivot-bolt 53.

. Each pair of shovel-beams 37 is connected together by an oblique brace54. Riveted to each brace 54 is an eye 55. eyes 55 are the lower ends offour depending rods 56. These rods 56 are supported by transversesleeves or pipes 57, which are supported by two rear cranes, as follows:Bolted to the rear faces of the right-hand two standards 29 are twobearing-pieces 58, provided with rearwardly-projecting bearing-ears 58at their upper and lower ends. Mounted in said ears or bearings 58' aretwo rear cranes 59. Each of said cranes is simply a round rod bent at anacute angle at 6() and extending downwardly and rearwardly. Connected tothe lower ends of these rear cranes by means of clips 61 is a transverserock-shaft 62, on the outer end of which is a forwardlyextending arm 63,which terminates in an eye which supports the outer end of the aforesaidsleeve or pipe 57. Secured on the lefthand end of rock-shaft 62 is anotched sector 64, integral with which is a clip 61, to which one of thecranes 59 is connected. Rigidly secured on rock-shaft 62 alongside ofsector 64 is a hand-lever 65, provided with a latch which engages saidsector 64, whereby said lever 65, rock-shaft 62, sleeve 57 rods 56, andhence the two right-hand gangs, are held at different heights, accordingto the position of said lever. Lever 65 extends forward from rock-shaft62 to form a support for the inner end of sleeve 57 which it does byembracing the inner left-hand rod 56, as shown in Fig. 1. When saidlever is depressed, sleeve 57 is Inserted in these TOO IIO

`raised through the intermediacy of rock-shaft 62 and its arm 63, andthe said shovels are lifted. When said lever is raised, the shovels arelowered.

The construction ofthe right-hand two rear cranes 59 and theirconnections to the corresponding' gangs has been described. rlheconstruction of the left-hand two rear cranes 59 and their connectionsto the two left-hand gangs is identical with that described, as clearlyshown in the drawings, and the same numerals indicate correspondingparts of both sides of the cultivator. It will be observed, however,that the inside right-hand shovel-beam 37 is elongated by means of abeam extension 66, to which the shank 38 is attached, as heretoforedescribed. By this means the inside right-hand shovel 67 is carriedbehind the inside left-hand shovel 67, the advantage of which is thatwhen plowing in trashy ground the said shovels will free themselves fromtrash, whereas if they were carried alongside each other and movedtogether the trash would accumulate upon them and be dragged along,which would prevent the shovels from working properly. The eXtension 66is used for the lirst plowing-only.

lFor the second plowing it is detached from the beam 37 by removingbolts 66', and the shovel-shank is connected to said beam, the length ofwhich is the same as that of the inside left-hand beam.

Surrounding each depending rod 56 is a Said springs 68 rest upon theeyes 55` and their upper ends are confined by collars 69. The eyes 55being slidableupon said rods 56, the springs 68 provide yieldingresistances to any upward pres- In the lower portion of each rod 56 areholes 70 for a Cotter-pin 71, which supports the rear portion of itsgang, it being directly beneath the aforesaid eye 55. By placing' saidpins 71 in different holes 70 the shovels may be supported at differentheights regardlessof the position of hand-levers 65. The rods 56 beingseparate from each other, it will be readily understood that they may beadjusted toward or from each other by sliding their horizontally-bentupper ends in the sleeves 57, which are provided with set-screws 72, bywhich the said rods 56 are held at the desired distances apart. Suppose,for example, that it be' desired to separate the two left-hand gangsWider apart than they are shown in the drawings. The rear ends of thegangs will be separated by drawing apart the rods 56. The front ends ofsaid gangs should also be separated an equal distance by adjusting thegang-couplings 35 upon the arch-rod 34. To separate the gangs as much aseight inches farther apart, the said couplings 35 may be reversed(placed end for end) upon the arch-rod.

The means for causing lateral motion of the gangs, either simultaneouslyor separate] y,

and for turning the carrying-wheels will now be described. These motionsare effected by two hand-levers 73 and 74, two foot-levers 75 and 76,sectors 77 and 7 8,.connectingrods 79, and three levers connected to thesway-bar 16. The hand-levers 73 and 74 are both fulcrumed on a bolt 80,which passes through a bearing 81, secured to and between theseatsupporting bars 7. (See Fig. 9 for a detail view.) Also fulcrumed onbolt 80, below said levers 73 andv 74, is a lever 82, the upper rear endof which is integral with or secured to the bottom of a notched sector83, above which and rigidly secured thereto by bolts 84 is a similarsector' 85. The hand-levers play between these two sectors. Theforwardly and downwardly extending end of sectorlever 82 is pivotallyconnected by a bolt 86 to a bracket 87, rigidly secured to the middle ofthe swaybar 16. The upper lever 73 has a latch that engages the uppersector 85, and the lower lever 74 has a latch that engages the lowersector 83. These latches may be kdisengaged from their sectors bymanipulating the releasing-handles 88 in the usual manner.

Riveted to the seat-supporting bars 7 just outside of the lever-bearing81 is a U-shaped fulcrum-piece 89, in opposite sides of which are twofulcrum-bolts 90 from which depend two foot-levers 91, having theirlower ends bent apart, as shown at 92. Adjacent to the two foot-levers91, respectively, are two rockshafts 93, having, respectively, dependingcranks 94 at their front ends, said cranks be- -ing pivotally connectedto the sway-bar 16 and having, respectively, two inwardly-extending'cranks 95. These last-named cranks 95 are connected to the foot-levers91 by rods 96, so that up or down motions imparted to the foot-levers bythe feet of the driver will be communicated to the sway-bar 16, movingthe latter to the right or th'e left, and thereby changing the angle ofthe carrying-wheels, which are mounted on pivot-axles, as alreadydescribed. The front bearings 97 of the rock-- shafts 93 are secured tothe oblique braces 5, and the rear bearings 98 of said rockshafts aresecured to the crane-standards 29. The upper hand-lever 73 at its lowerend is ccnnected by a rod 99 to the inner right-hand crane 32 by meansof a clip 100 secured to the latter. The other hand-lever, 74, isconnected by a rod 99 to the inner left-hand crane 32 by means of a clip100 secured to the latter. A rod 102 connects said inner front crane 32to the outer rear crane 59, said rod being' connected to clips, asshown, and on the righthand side of the plow a rod 103 connects theinner front crane 32 to the outer rear crane 59, said rod beingconnected to clips, as shown. Said rods 102 and 103 are connected atsuch points of the front and rear cranes that when the front cranes 32are moved laterally the rear cranes 59 connected theretowillbemovedlaterally the same distance by means of rods 102 IOO VLIO

and 103. The eect of this equal movement of the front and rear of eachgang is that the shovels will preserve the same angle relatively l tothe frame of the cultivator regardless of the lateral adjustment of thegangs. This is a great advantage over any other cultivator or' which weare aware.

The operation of the hand-levers 73 and 74 is as follows: To move allfour gangs together in the same direction, (either to right or left,)turn the longer level' 74 without releasing its latch. This will alsochange the angle of the carrying-wheels to correspond with the movementof the gangs. To move the righthand pair of gangs only, turn the shorterlever 7 4, releasing its latch. To move the left-hand pair of gangsonly, turn the longer lever 74, releasing its latch. To change the angleof the carrying-wheels with the feet, depress one of the foot-levers 91,according to the direction in which the wheels are to be turned. The twopairs of gangs may be drawn so closely together that the inner shovelswould touch if one of said shovels were not set behind the other, asalready described. The sectors 83 and 85 being rigidly secured together,it follows that when either lever 73 and 74 is turned without unlatchingit will turn the other lever, and thereby swing both pairs of gangssimultaneously.

While we have only shown and. described shovels for stirring the earth,we wish it understood that disk or colters will practically answer forthe same purpose, and we reserve the right to utilize either in place ofshovels, if desired.

Having now fully described our invention, what we claim as new, anddesire to secure by Letters Patent of the United States, is-
